Something is also wrong with the rear end In my 94 yj. After about ten mintutes of driving it will start to make a friction created noise in the rear and you can feel a resistance pulling the jeep to a stop. The guy pulled the cover I bought it off of and said there are no visual failurs with the spiders and the ring, He said the jeep did just get new brakes all around and maybe they need adjusted in the back or something. Any ideas?

Well I jacked it up today. The pinion has more play then it seems like its supposed too. The brakes are good nothing hanging up there. The drive shaft u-joints seem ok no play. It seems like I was hearing something in the passenger side axle tube like a bearing or something. I could spin the axles freely with my hand nothing sounded like when I drive it. I am still stumped, I will tear it down tomorrow probably.
